ICT systems and their usage

The GCSE ICT course is all about ICT systems. You need to know the general structure of information systems, and how they work; the role of input, output, processing and feedback; and the integration of ICT devices and ICT information systems.

What is an ICT System?

An ICT system is a set-up consisting of hardware, software, data and the people who use them. It commonly includes communications technology, such as the Internet.

ICT and computers are not the same thing.

Computers are the hardware [hardware: the physical components of a computer ] that is often part of an ICT system.

This is why your GCSE is not just about computers but about how, why and when people use them. It is the power of computers and communications that has allowed ICT systems to become so important. Like any piece of equipment, the important thing about it is what it lets us do.

ICT Systems are used in a number of environments, such as:

  • offices
  • shops
  • factories
  • aircraft
  • ships

They're also used in fields such as:

  • communications
  • medicine
  • farming

ICT Systems are everyday and ordinary, yet extraordinary in how they can add extra power to what we do and want to do.

The importance of ICT systems

By using ICT systems we are:

  • more productive - we can complete a greater number of tasks in the same time at reduced cost by using computers than we could prior to their invention
  • able to deal with vast amounts of information [information: data with context or meaning ] and process it quickly
  • able to transmit and receive information rapidly
